Answer:
$149.50
Step-by-step explanation:
Width = x
Length = 2x - 5
Perimeter of the room = 5x
Perimeter of the room = 2(length + width)
5x = 2{(2x-5) + x}
5x = 2(2x - 5 + x)
5x = 4x - 10 + 2x
5x = 6x - 10
5x - 6x = -10
-x = -10
x = 10
Width = x = 10
Length = 2x - 5
= 2*10 - 5
= 20 - 5
= 15
Perimeter of the room = 5x
= 5 × 10
= 50 square foot
If carpet costs $2.99 a square foot, what the total cost to carpet the living room
Total cost = $2.99 × 50
= $149.50
Answer:
5
Step-by-step explanation:
You will multiply 1/3 by 3. This equals 1. 5^1 equals 5.
Ill say, C) Place the compass' point on the other end of the segment.
the area is 254.34 sq. ft.
Answer:
5−x²+2xy−y²
Step-by-step explanation:
5 - (x-y)²
Rewrite
(x−y)² as (x−y)(x−y) so
5−((x−y)(x−y))
Expand (x−y)(x−y) using the FOIL Method
Apply the distributive property.
5−(x(x−y)−y(x−y))
Apply the distributive property
5−(x⋅x+x(−y)−y(x−y))
Apply the distributive property
5−(x⋅x+x(−y)−yx−y(−y))
Simplify and combine like terms
Simplify each term
5−(x²−xy−yx+y²)
Subtract yx from −xy
5−(x²−2xy+y²)
Apply the distributive property
5−x²−(−2xy)−y²
Multiply −2 by −1
5−x²+2xy−y²
